REGO C-19434B350 1/2″ ASME Cryogenic CO2 Relief Valve 350 PSIG EPDM O2 Clean

REGO C-19434B350 1/2″ ASME Cryogenic Gas Relief Valve – 350 PSIG – CO2 Service

RegO C-19434B350 ASME-rated cryogenic pressure relief valve designed specifically for carbon dioxide (CO2) gas service. The valve features a durable brass body, 1/2″ male NPT inlet connection, stainless-steel spring, brass seat retainer, and EPDM synthetic rubber seat disc.

Factory set at 350 PSIG (24.1 barg) with an ASME-rated relief capacity of 711 CFM/Air. The valve is designed to begin relieving moderately excessive pressure and open to full discharge capacity as pressure rises beyond its predetermined point. It is bubble-tight at 95% of set pressure and reaches full flow at 110% of set pressure.

The valve is ASME rated and certified, oxygen cleaned per CGA G-4.1, rated for gas service, and 100% factory tested. Operating temperature range is -40°F to 165°F (-40°C to 74°C).

IMPORTANT: Pipe-away adapter is NOT INCLUDED and is sold separately. RegO specifies the B-19434-6 with 1″ FNPT outlet as the available pipe-away adapter for this series.

For safety-critical pressure relief applications, buyers should verify the set pressure, service compatibility, certification requirements, condition, and installation requirements before use.

RegO’s current technical sheet specifically identifies the C-19434B350 as the 350 PSIG model with a 711 CFM/Air ASME relief capacity. The C-19434B series is intended for CO2 service, uses a brass body and EPDM seat disc, and is 100% factory tested.
